I am Dan

Dan I am. I have been an Oracle DBA and Oracle Application Server admin since Oracle7 and OWS 2.x. I have some certifications: OCM, OCP DBA, OCA 10gAS, RHCE, and some others that are now meaningless. I spend most of my time these days on Exadata, RAC, clustering, and high availability. I'm involved in the IOUG, the Exadata SIG, and the Norris family. I work for Oracle Corporation in the Exadata Team. The views expressed on this blog are mine and do not necessarily reflect the views of Oracle.

Collaborate 09 starts on Sunday, May 3 (a few days from now!) in Orlando. I’ve been offline for several weeks (more on that later), but will be returning to the world of computers and technology in full force in Orlando. I’ve had a few inquiries about whether or not I’ll be at Collaborate, so I […]

The RAC SIG, Oracle and IOUG are thrilled to present the hands-on event dubbed “RAC Attack!” at Collaborate09 in Orlando, FL. It is a half-day University Session in the IOUG Forum scheduled for the morning of Thursday, May 7th. Each participant will have their own private RAC cluster to use. You’ll be able to install […]

I’ll be the first to offer a large congratulations to Jeremy Schneider on being the most recent appointment to the Oracle ACE program. He certainly deserves it (I nominated him, so I suppose I would think so) and I continue to look for great things to come. Jeremy is the main creator of the IOUG […]

Those of us that have dealt with RAC environments for a while are familiar with the behavior of Oracle Services in an Oracle Cluster. Services are an essential component for managing workload in a RAC environment. If you’re not defining any non-default services in your RAC database, you’re making a mistake. To learn more about […]

Blink and 3 weeks goes by and I forgot to blog any new updates! I’ve got a few new entries that will be coming along after my last 2 weeks being up to my eyeballs in Oracle Application Server 10.1.3, but that will wait. The exciting news is: I’m going to present at Hotsos Symposium […]

Here’s a good reason to become an IOUG member or, if you already are a member, a good reason to dig out that username/password to the IOUG website. The most recent issue of the IOUG publication SELECT Journal contains several great articles (if I do say so myself) about Oracle RAC. I contributed one article […]

As one of the organizers of the IOUG RAC Attack! event, I may have a slightly partial viewpoint, but I think the event overall went very well. The hands-on lab was especially popular and I think participants in the hands-on lab all got to learn at least a few new things. If you’ve been to […]

Many of you have (hopefully) heard of the IOUG RAC Attack! event taking place yesterday and today in Chicago. We had a great first day yesterday with many great technical sessions and the first-day lab guinea pigs didn’t find many bugs or issues in completing the lab exercises and tests. Overall, the format is working […]

The Oracle RAC SIG and the IOUG are co-sponsoring the IOUG “RAC Attack” event and if you haven’t yet heard about it, you might want to check it out. The event runs for 2 days, August 4-5, in downtown Chicago and will bring together some excellent presenters as well as the opportunity for hands-on experiences […]

I’ve been to more than one RAC customer site and seen several different ways to misconfigure the listeners for a RAC cluster. This post describes how I usually configure the listeners and their associated instance parameters normally. This really has nothing to do with TAF or connection load balancing, those those features may not work […]
